フアレンシヤル装置の差動制限装置。[Claims for Utility Model Registration] Equipped with a vane type oil pump, the differential of the differential device is controlled by the discharge fluid pressure generated in accordance with the amount of relative rotation between the rotor and the housing that constitute this pump. In the differential limiting device configured to limit slip, the housing includes a cam ring member having an inner circumferential surface of a cam ring on which vanes attached to the outer periphery of the rotor slide, and the housing is attached to both sides of the cam ring member, first and second ring members forming sides of the housing, the rotor having a vane back pressure hole for obtaining vane back pressure for pressing the vane against the inner peripheral surface of the cam ring; The first ring member is provided with a fluid introduction passage for introducing discharge fluid generated by relative rotation between the rotor and the housing into the vane back pressure hole, and the second ring member is provided with a fluid introduction path that introduces discharge fluid generated by relative rotation between the rotor and the housing into the vane back pressure hole. A differential valve comprising: a fluid outlet communicating with the vane back pressure hole; and a variable throttle mechanism capable of adjusting the flow rate of the fluid flowing out from the vane back pressure hole to the fluid outlet depending on the fluid pressure. Differential limiting device for serial devices.
